Both are not specifically aimed at content for passing exams but still offer plenty of information that will help.

Finally, there are the Office 365 Virtual Labs for IT Pros, again free from Microsoft. This will allow you to get you hands dirty in a full virtual environment. This is especially handy for the SMB types who probably don’t have the infrastructure to implement Office 365 Federation.

I’m sure as time goes on there be lots more becoming available so stay tuned.
